Our latest project is a 22-250 in the AR-10(type) platform. Ours requires no special magazines, no proprietary lower, no BS, just a simple, very accurate, built the way you want it, coyote killing machine. we lightened the barrel to bring the weight of the entire rifle right at 8.9lbs. We have two production models, the Spade and the LRPR. If you want a different component, just ask, we build our rifles to your needs and wants.
